Title: Transmission of operating information in telephone installation - involves common interface circuit and several control desks with displays
Inventor: BAUDOIN MICHEL
IPC: H04M3/62
Filed: 1975-04-09
Abstract: Important telephone installations use an interface circuit with a number of operator desks containing display lamps, signs and control switches. Signals from a memory enable an operator to receive visual information about calls. A common interface circuit (IFC) is connected via a data transmission channel (V) to a number of operator control desks (P1). The interface circuit operates under the control of a common control circuit (CCC) via an exchange channel and contains a memory containing information for display at the operator desks. A register receives modification data while a transmission circuit (EM) contains the data for a particular desk. The control desk contains indicators (A1, A2) signalled from reception circuits (REC) and also push buttons (BP1, 2) which control a coder (CO) for the control circuit (CCC).

Title: Rotating machine with high power to weight ratio - includes two superconducting windings and one normal winding
Inventor: POUILLANGE JEAN-PAUL
IPC: H02K55/04
Filed: 1975-04-16
Abstract: The rotating machine has its power-to-weight and power-to volume ratios increased by making the first of its three windings superconducting. The second is also superconducting whilst the third is a normal type. The first and third windings are homokinetic and they are linked to a servomechanism that alters their relative angular positions according to the couple transmitted by these two windings. The third winding is connected directly to the shaft. If the first winding is polyphase and supplied by ac and the third winding is supplied with dc, then the second winding is similar to the first.

Title: Pneumatic tool lubricant dispenser - has lubricant reservoir built onto air feed and flow from reservoir to feed is via microporous pastille
IPC: B25D17/26
Filed: 1975-07-30
Abstract: The lubricant dispenser for pneumatic tools obtains a steady drip of lubricant into the compressed air feed (5, 6). An oil reservoir (1) is built onto the air feed, and oil flow through the pipe (8) which connects from the reservoir to the air feed is controlled by a microporous pastille. The reservoir takes the form of a moulded cup (1) with a transparant screw cap (2). The cup is mounted on the air feed in a prominent visible position, and the feed traverses the base of the cup. A drilling which aligns normally to the feed connects from the cup (12) to the feed (13). The microporous pastille is held in place by a tubular bolt with a hexagonally socketed head. The rate of oil discharge is adjustable by tightening the bolt onto the pastille.

Title: Protected flashing indicator circuit - has dynamic feedback to multivibrator and power transistor to correct short circuit and incorrect load to lamps
Inventor: ROUSSET MICHEL
IPC: B60Q11/00
Filed: 1975-10-07
Abstract: The flashing indicator circuit has a multivibrator (1) driving a power transistor (40) through an operational amplifier (31). The power transistor in turn switches current to the lamps. The lamp signal (51) is also delivered to a stabilised protection circuit (50) which also receives an input (H) from the multivibrator. The protection circuit has elements (68) which are sensitive to the timing of the multivibrator and detect cases of overload, underload and short circuit. The output (69) from the elements is fed back to the multivibrator (71) and operational amplifier (70). The effect is to regulate the timing of the multivibrator and/or switch off the power transistor under instance of excess load. The protection circuit may also be used to illuminate warning lamps to indicate a fault.

Title: Arc-extinguishing circuit breaker - uses auxiliary separating contacts operating in magnetic field to lengthen and extinguish arc
IPC: H01H33/18
Filed: 1975-12-03
Abstract: The mobile contact of the circuit breaker is a vertical rod (28), which in its operated condition, rests between two spring loaded contacts (12, 14) at its top end. The rod is lowered and separated from those contacts to break the circuit. As it travels downwards, another pair of arc-extinguishing contacts (42, 44) is separated by a cone-shaped unit (60) of refractory material mounted on the vertical rod. Simultaneously, a magnetic field is created in a coil (32) around the electrodes and the arc length is increased. This causes it to be extinguished. The whole unit is sealed in a container of sulphur hexafluoride. The design provides simple mechanical linkage and rapid arc extinction.

Title: Liquid cooling control in dry tower cooler - using cooled liquid recirculation and liquid injection between cooling elements
IPC: F28F27/00
Filed: 1976-09-28
Abstract: A dry tower with a series of cooling elements pref. finned tubed bundles is used to cool a hot fluid to a required temp. To prevent the cooled fluid dropping below a certain critical temp. an adjustable supplementary amount of fluid can be passed through some or all of the elements. A supplementary flow through all of the cooling elements is obtd. by putting in a recirculation, complete with pump and valve for control and recycling some of the cooled fluid to the hot fluid header at the inlet to the elements. With several cooling elements in series the flow through some of them is increased by injecting some of the hot fluid at the inlet to some of the elements in the series. The hot fluid for injection is taken off from the inlet line to the first cooling element and is branched into the required elements downstream from the first. A combination of the recycling circuit and the injection circuit both with adjustable flow can be used to provide the supplementary flow. Used in dry cooling towers for liqs. that may change state or begin to crystallise if cooled too much. Towers allow the temp. control of the final cooled liquid.

Title: Activated sludge plant for purificn. of waste water - uses suction of aeration impeller to recycle sludge from settlement tank
IPC: C02F3/16
Filed: 1976-12-09
Abstract: The liq. for treatment first enters an aeration tank provided with a rotary impeller to aerate the surface. From the aeration tank liq. passes to a final settlement tank from which activated sludge is recycled to the aeration tank. The means for recycling sludge comprises of the settlement tank into the suction zone of the surface aerating impeller. Transfer of liq. from the aeration tank to the settlement tank is pref. by overflow. The aeration tank can be comparatively shallow, without a circulation chimney leading up to the impeller; the top of the sludge recycling pipe then delivers just below the impeller. Alternatively, the aeration tank can be deep, with a circulation chimney rising towards the impeller; in this case the sludge recycling pipe delivers into the chimney.

Title: Low pour point transformer oil from paraffinic crude - by fractionation, solvent extraction and solvent dewaxing in three-phase system
Inventor: REID LLOYD E
IPC: H01B3/22
Filed: 1977-02-07
Abstract: Prodn. of transformer oil with a low pour point (below-40 degrees F) from a waxy distillate fraction of a paraffinic crude comprises first subjecting the distillate, which has a 5-95% boiling range of 595-755 degrees C (pref. 600-735 degrees F) at atmospheric pressure, to solvent extraction to produce an extract and a raffinate. The raffinate is then subjected to solvent dewaxing at -10 to -40 degrees F (pref. -20 to -30 degrees F) to form a 3-phase slurry contg. solid wax, an oil-rich liq. phase and a solvent-rich liq. phase. The slurry is filtered at -10 to -40 degrees F (pref. -20 to -30 degrees F) to separate the solvent-rich pha se as filtrate from a wax cake contg. the oil-rich phase. The solvent is then removed from the filtrate to recover the transformer oil. The process avoids the use of special fractionating columns and gives products with a low cloud point (e.g. -23 to -29 degrees F).
